Control of a Multi-Pulse SVM Based Unified Power Flow Controller (UPFC)

2020 IEEE Region 10 Symposium (TENSYMP), 2020
This paper presents the implementation and control of Unified Power Flow Controller (UPFC) to control active and reactive power independently in a transmission line. It is basically consists of two voltage source converters one is Static Synchronous Compensator (STATCOM) and another is Static Synchronous Series Compensator (SSSC).

Visualization and investigation of unified power flow controller (UPFC) nonlinearity in power flow

2003 IEEE Power Engineering Society General Meeting (IEEE Cat. No.03CH37491), 2004
This paper investigates the nonlinearity of unified power flow controller (UPFC) on the power system load flow problem. Since the various UPFC parameters equations are nonlinear, a form of vector presentation in complex power plane is used to visualize the effect of different control parameters of UPFC on line power transfer.

Fast reliable unified power flow controller (UPFC) algorithm

Seventh International Conference on AC and DC Transmission, 2001
Growth of electric power demand leads to growth in electric power systems. So AC transmission systems must be controlled fast enough and practical enough to handle the variation of power system conditions. Many traditional controllers were used before with the design of transmission systems but greater operating flexibility and better utilization of ...

Unified power flow controller (UPFC) based on chopper stabilized multilevel converter

PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 2002
A system of class B choppers equalizes the DC voltages of the back-to-back multilevel converters of the UPFC thus removing the constraint that the voltages of the series and the shunt converter must operate at a fixed ratio. This allows the UPFC to operate with independent controls over the real power and the reactive powers on both sides.
